Question

Assume that human body temperatures are normally distributed with a mea of 98.18°F and a standard deviation of 0.61 F a. A hospital uses 100.6 F as the lowest temperature considered to be a fever. What percentage of nomal and healthy persons would be considered to have a fever? Does this percentage suggest that a cutoff of 100.6 F is appropriate? b. Physicians want to select a minimum temperature for requiring further medical tests. What should that temperature be, if we want only 5.0% of healthy people to exceed it? (Such a result is a false positive, meaning that the test result is positive, but the subject is not really sick.) Click to view page 1 of the table. Click to view page 2 of the table. a. The percentage of normal and healthy persons considered to have a fever is% (Round to two decimal places as needed.) Does this percentage suggest that a cutoff of 100.6°F is appropriate? ○ A. O B. O C. O D. Yes, because there is a small probability that a normal and healthy person would be considered to have a fever Yes, because there is a large probability that a normal and healthy person would be considered to have a fever. No, because there is a large probability that a normal and healthy person would be considered to have a fever. No, because there is a small probability that a normal and healthy person would be considered to have a fever. b. The minimum temperature for requiring further medical tests should be | Round to two decimal places as needed.) | F if we want only 5.0% of healthy people to exceed it.
